How do we calculate my vote power?
What determines the vote power rating for ballot measures: Representation: how much weight one vote carries here compared with a statewide vote — the smaller the district, the more each vote counts. You have more power in ballot measures because you vote directly on the policy.
Representation: Above average · 64 out of 100
This district is a good deal smaller than its state, so each vote here carries more weight than a vote in a statewide race. About 288,512 people live here.
Show the representation math
score = 50 + 50 × ln(state population ÷ this district's) ÷ ln(50,000) = 50 + 50 × ln(6,191,814 ÷ 288,512) ÷ ln(50,000) = 64.17, measured against a statewide vote in MO (grades: 66+ high, 55+ above average, 33+ average, otherwise low; a statewide race is the 50 baseline)
Above average representation + a direct vote on the policy → My vote power: High.
